近年来接枝共聚物引起了各国研究工作者的很大注意。已经创立各种各样的制备接枝共聚物的合成方法;其中用預先形成大分子过氧化物引发接枝共聚的方法研究得最多。大分子过氧化物可以用臭氧、空气或其他氧化剂来氧化高聚物,或在氧的存在下用γ射线照射而得到。由于这些氧化反应和接枝共聚反应大都是在异相中进行的,故对反应动力学以及其结构与性能关系的研究都带来困难。
In recent years, graft copolymer has attracted great attention of researchers from all over the world. A wide variety of synthetic methods have been established for the preparation of graft copolymers; the most studied is the method of initiating the graft copolymerization with macromolecular peroxides. Macromolecular peroxides can be obtained by oxidizing the polymer with ozone, air or other oxidants, or by gamma irradiation in the presence of oxygen. Since these oxidation reactions and graft copolymerization reactions are mostly carried out in heterogeneous phase, the research on the reaction kinetics and the relationship between its structure and properties are all difficult.
